HEATER CONSTRUCTION.

Specification of Letters Patent.

Patented Nov. 13, 1917.

Application filed December 9, 1914. Serial No. 876,272.

residing at New Brunswick, in the State of New Jersey and county of Middlesex, have invented a new and useful Improvement in Heater Constructions, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention has general reference to heater constructions and more particularly to the features incident to its structural arrangement. Heretofore two types of heater have been employed for the purpose of heating the water supply required for domestic usage. One consisted of a heater of small capacity which heated the water contained within a comparatively large storage tank.

/Vhile this type gave service it was wasteful and extravagant due to the loss by heat radiation when keeping a large tank hot. The other utilized a heating conduit of capacity meant to be large enough to sufliciently heat the flow from a faucet under normal pressure, and the burners of which were automatically lighted from a pilot flame when the gas valve Was opened by the water pressure. At times this type was too large and frequently too small when an inordinate supply was required. Conditions under one extreme made it wasteful and under the other extreme temporarily insufficient. My new type of water heater involves a comparatively small storage supply with a large capacity heating with means which are hereinafter explained form embodying my invention, it should be understood that the means only exemplifies one of many diversified mechanical forms with which the principle of my invention' may be properly applied.

Figure I is a side elevation of an exemplifying heater construction embodying my Invention.

Fig. II is an end view of Fig. I showing certain parts broken away.

Fig. III is a view corresponding to Fig. I with the front of the casing removed in sec- 7 tion to disclose the interior.

character A comprises suitable legsfa, a perforate base a supporting near one end one or more burner seats a one of which is well shown in Fig. III. The front wall a of the casing is provided in its lower part. with a door a whereas the rear wall a of the casing is provided with an opening near its top which is in connection with a stack 07.. It will be noticed that the casing involves a double set of walls the inner one of which may be cast iron and the outer any suitable insulating material. One of the ends, namely the one at the left as appears in Fig. III is provided near its bottom with a number of openings at", in this instance four, to correspond with the number of burners employed in this particular exemplification. The'openings a are disposed substantially on a level with the tops of the burner supports a :Some distance higher up the end a of the casing is provided with additional openings 01 which reference character should be assumed as applied to an opening inboth walls as a unit. Actually there are six of theseopenings and their purpose will hereinafter appear. The .upper extremity of the end a is fashioned with an approximately semicircular recess a of maximum dimensions. The opposite end a of the casing is provided midway with a large -tions 6 and return bends b.

opening (1 corresponding in height with the height of the door a though positioned somewhat higher up. This opening a should similarly be understood to extend through both walls of the end or of the easing, as is again apparent in Fig. III. The upper extremity of the end a is provided with a recess a similar to the recess a. A removable panel a is adapted to close the opening a when affixed as by screws a. The upper and lower edges of the panel (1 are provided with six equally spaced grooves, those above being designated as a" and the lower ones as (1. Each superposed pair of grooves a and (Z18 is disposed in the same endwise plane as one of the openings a These grooves are best seen in Fig. II, such parts as are broken away having been so shown for the very purpose of disclosing these grooves.

Seated'and suitably packed within the recesses a and a so as to effectually close the upper end of the casing A and be in turn partially enveloped thereby is an elongated storage-tankB of smaller capacity than has ,heretofore been generally employed. One

end of the tank, namely the left end is provided with a conduit inlet 1). Above, a pipe 6 will be presumed as leadin to the faucet. The outlet 6 communicates Iiy means of a flange connection 6 with a manifold 6 provided below with an opening I) intended for the insertion of the sensitive element of a thermostat. While this manifold has six outlet openings corresponding with and spaced as the grooves a connections with only one will be described. Connected with the outlet of the manifold 72 is the male part b of the common type of union. The female part b of this union is supported upon the upper inlet extremity b of azigzag interiorly positioned portion of the water conduit. This conduit 'is clearly shown in both Figs. III and V to embody the well known principle of both a downward and an upward flow. According to my invention however, the interiorly disposed portion or portions of the conduit with its alternately inclined interjacent sections are substantially flat in its entirety so as to be capable of lying within a vertical plane as is well shown in Fig. IV. Such alternate inclination involves above straight interjacent sections 6 connected by return bends b through which the water travels downwardly, next a directly downwardly extending portion'b leading into a T 6 to which a drain cock b is connected. This cock projects outwardly through the groove (1 as is shown in Figs. II and III. Thereafter the travel of the water is upwardly through straight alternately inclined sec- The outlet extremity 6" passes through .the opening a and carries the female part a? of another union. The male part b of such union is likewise connected with one of the inlets of a manifold 6 which is in turn connected at b with a pipe I) communicating with-the inlet 7).

It should now be manifest that owing in part to the configuration of so much of the water conduit as is disposed within the confines of the casing, and in part to the provision of the removable panel a in one of the interior conduit units may be withdrawn through the opening a after disconnection from the manifolds Z) and 6 Thus a facility is occasioned by removing any section of the conduit which has developed a flaw or for any other reason, and this may furthermore be accomplished independently or without disturbing in any wise the connection of any other conduit section.

A plurality and in this instance four burners C, having inlet ends 0 extending through the openings a and opposite extremities 0 are suitably mounted upon the supports a The burners 0 each carry a plurality of removable stools c Secured to the inlet ends '0 outwardly of the end or of the casing, is a mixing valve 0? connected by a pipe length 0 with a gas manifold 0 leading through the agency of a bent pipdconnectiori 0 to a valve 0 in connection with the source of fuel supply. The

operation of the .valve 0 is controlled by means of the-type of thermostat 0 earlier referred to and which comprises a sensitive tube 0 adapted by means of a flexible connection 0 to actuate the valve stem 0 I claim 1. A heater construction comprising a casing, a storage tank thereon, heating.

means 111 communication therewith, a zigzag water conduit above said heating means and connected with said tank, opposite extremities of said conduit being detachably connected, and a panel disposed endwise of said conduit and adapted to permit the withdrawal of the conduit therethrough, said panel being fashioned with grooves for the reception of said conduit extremities whereby to facilitate fitting and holding of the panel in place.

2. A heater construction comprising a casing, a tank above, an elongated burner construction below, a plurality of laterally adjacent zigzag water conduits having longitudinally extending interjacent portions and communicating with said tank, inlet and outlet manifolds communicating with inlet and outlet ends of said conduits respectively and with said tank, said inlet and outlet ends being detachably connected to said manifolds, and a removable panel in one end. of said casing through which individual of said conduits may be withdrawn independently of each other, said panel being fashioned with grooves in the 1.0

in number to said individual conduits, said inlet. and outlet ends being seated 1n said grooves whereby to determine the proper position of and hold said panel place.

3. In an apparatus for heating and causing the circulation of a fluid, a conduit system which includes a zigzag passage comprising elongated interjacent portions and having a continuously downward direction from its inlet to its discharge end, a second zigzag passage comprising elongated interjacent portions located below the first and having a continuously upward direction from its inlet toward its outlet. end, and a duct which connects the lower discharge end of the first mentioned passage and the lower intake end of the second mentioned passage, heating means located below said tank from which service water is adapted to be drawn, said tank being located above and connected to. said passages, an inclosing casing which embraces said passages, tank and heating means whereby heat from the latter is directly applied to the tank and, a removable panel at one endof said casing, said panel being provided with a groove in each of its to and bottom edges for the reception of sectlons of said passage, the engagement being such that said zigzag passage may be withdrawn endwise from beneath said tank without disturbing any connections of the latter.
